Maintenance

Only specialist personnel may perform maintenance on the spindle.

The HF spindle must be shut down before any maintenance work.

Ü

Make sure that the shaft of the HF spindle has come to an absolute stand-
still.

Ü

Before carrying out any work, read the corresponding section of the man-
ual carefully again.

Ü

Observe the manual of the machine in which the HF spindle is installed.

Ü

Observe all safety instructions and safety rules.

12.1

Ball bearings

Note: Foreign matter reduces the service life.

The  HF  spindle  bearings  have  lifetime  grease  lubrication.  This  means  that
they do not require maintenance.

u

Do not lubricate the ball bearings.

u

Do not apply grease, oil, or cleaning agents to the openings of the HF
spindle.

12.2

Daily cleaning

To ensure that the HF spindle functions safely and accurately, all contact sur-
faces of the HF spindle, the mount for the HF spindle, the tool mount, and the
tool holder must be clean.

Note: Foreign matter reduces the service life.

u

Do not use compressed air to clean the HF spindle.

u

Do not use ultrasonic cleaning on the HF spindle.

u

Do not use steam jets to clean the HF spindle.

This could cause contamination to enter the bearing area.

12.2.1

Before commencing work

Ü

Check that all surfaces are thoroughly cleaned and free of dust, grease,
coolant, machining residues, and metal particles.

Ü

Check that the HF spindle is free of damage.

Ü

If the HF spindle is equipped with sealing air, always switch this on during
cleaning.

Ü

Only use a clean, soft cloth or a clean, soft brush for cleaning.

12.2.2

With every tool change

Ü

Ensure that the tool mount and tool shank are clean.

Ä

Remove any soiling.
